3 of these and the beach isn't so bad. You still can't make me go past my knees, or where I can't see the bottom, though. I blame my mother. Years of going to lake Michigan and being threatened with undertow and rip currents will do that to a girl. Or is it undertoe? Spellcheck says undertow. Either way. Beer is the key to beach survival. No one told me that when I was a kid, before fun was invented, obviously.
